This healthy and flavourful recipe is from Gourmet Magazine (Feb. 2008). You can also use it to make waffles.
If the batter is too thick, just add a little more buttermilk.
Best with maple syrup, of course! ;)
Meanwhile, whisk together flour, baking powder, baking soda, cinnamon, nutmeg, and salt in a large bowl.
Stir egg, butter, brown sugar, remaining 3/4 cup plus 2 tablespoons buttermilk, and oat mixture into dry ingredients until just combined.
Heat a griddle over medium heat until hot and lightly brush with oil. Working in batches, pour 1/4 cup batter per pancake onto griddle and cook until bubbles appear on surface and undersides are golden-brown, about 1 minute. Flip with a spatula and cook other side, about 1 minute more. (Lightly oil griddle between batches.).
